Answer:
-26
Step-by-step explanation:
well add the negative numbers first so you get
-17-18=(-35)
then you add 9 so its (-35)+9=26
Like fractions are fractions that have the same denominator. In option D, both denominators are 7. Therefore, they are like fractions.
7056. 1008 x 7 = 7056. 7056 / 441 = 16
All angles in a triangle add up to 180
So 79+37=116
180-116=64
Y=64
Hope this helps
